Energy Penetration Tests:
Pink Poly vs. Statshield® Metal-In
Test results per ANSI/ESD S11.31 for evaluating the Performance of Electrostatic Discharge Shielding Materials – Bags tests for energy penetration calculated seen inside an 8 x 10 inch shielding bag using an ESD Simulator generating a pulse discharge of 1,000 volts to the exterior of the bag:
PINK POLY BAG:
STATSHIELD® METAL-IN BAG:
*1,372 nJ
25 nJ
* 27 times the amount of energy penetration allowed by ANSI/ESD S11.31, ANSI/ESD S541 and ANSI/ESD S20.20. 55 times more energy penetration than our Statshield® Metal-In Shielding Bag.
Pink Poly Bags do not claim to provide shielding.
The minimum recommended technical requirement of Table 1 of ANSI/ESD S20.20 for ESD Packaging Shielding is < 50 nJ tested in accordance with ESD S11.31.
nJ is the abbreviation for nanojoule.
A Joule is an unit of energy: the International System unit of energy or work, equal to the work done when the application point of a one newton force moves one meter in the direction of application.
Nano is one-billionth or 10E-9 (if you had 1 nanojoule and wanted to express it as a Joule, you would move the decimal point 9 places to the left or .000000001 Joule).
Per ESD S541 section 6.2 Outside an EPA “Transportation of sensitive products outside of an EPA shall require packaging that provides:
1. Low charge generation.
2. Dissipative or conductive materials for intimate contact.
3. A structure that provides electrostatic discharge shielding.”
Per Table 1 of ANSI/ESD S20.20-1999 the energy penetration test per ANSI/ESD S11.31 for evaluating the Performance of Electrostatic Discharge Shielding Materials – Bags to be < 50 nJ.
